Antibacterial Activity of Citrullus Colocynthis against different types of bacteria

Abstract

In the present study, antibacterial efficiency of citrullus colocynthesis (L.) schrad was Studied on seven types of pathogenic bacteria isolated from different sites infection, Escherichia. coli, Klebsiella pneumonia, Proteus mirabilis, Streptococcus pneumonia ,Streptococcus agalactia, Streptococcus mutans and Staphylococcus aureus. Water and ethanol extract were used for antibacterial assay. The inhibitory effects of this extracts were compared with standard antibiotics, cefotaxime. The ethanolic extract showed inhibitory activity against Escherichia. Coli, Proteus mirabilis, Staphylococcus aureus, Streptococcus agalactia. Water extract exhibited less or no activity against all types of bacteria. Results Indicated that ethanolic extract has a similar inhibitory effect with cefotaxime.
